Subject: [PATCH 02/11] ARM: imx: use dynamic mapping for CCM
Date: Sun, 26 Apr 2015 22:31:03 +0800	[thread overview]
Message-ID: <1430058672-9267-3-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <1430058672-9267-1-git-send-email-shawn.guo@linaro.org>

Replace the static mapping of CCM block in clock drivers with dynamic
mapping.
